Saying "Au Revoir" to the Cats

I know I kid myself that these cats realise I come to see them regularly, but I felt I had to say farewell, since I am going to be away for a month. I'm not sure how many of them noticed though - it was sleep central.

Of course Bruiser had also been asleep but woke up with menaces to make it clear he hated everything, especially me, whether awake or not.
